>...was the color that provided the sharpest visual acuity I think it changes considerably based on the environment and the user. I do some 10 meter air rifle competition, and the sighs have filters in them to let you choose different colors. I can notice a big difference based on the lighting, and at a competition different people will have settled on different colors.
